NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface networkInterface in networkInterfaces)
{
Console.WriteLine(networkInterface.Description);
}
How can I get the IP address from each networkInterface ?
Thx...

You can try something like this:
foreach (NetworkInterface adapter in adapters)
{
IPInterfaceProperties props = adapter.GetIPProperties();
UnicastIPAddressInformation unicastAddress = props.UnicastAddresses.FirstOrDefault(address => address.PrefixOrigin == PrefixOrigin.Dhcp);
Console.WriteLine(unicastAddress.Address);
}

Hiya,
Dont kniow if anyone can help - but worth a shot. I am writing an app that takes in 3 values from 3 columns in a CSV (account number, start date, end date). The code i have at the mo only reads 1 column at a time, and i am not too sure how i can read the 3 values and pass them to the stored proc to get processed. The proc takes the values and processes them line by line. At the moment it reads all the column values and inserts it for accounts, date1a, and date2a, whereas i actually only need column 1 for accounts, column 2 for date1a, and column 3 for date2a. I would appreciate any feedback to get a solution as google is not my friend right now  .
So far my code looks like this:
private void btnImport_Click(object sender, EventArgs e)
{
try
{
lblShowDetails.Text = "Importing accounts...";
this.Refresh();
DataSet ds = new DataSet();
if (ofd.ShowDialog() == DialogResult.OK)
{
FileStream fs = new FileStream(ofd.FileName, FileMode.Open);
StreamReader s = new StreamReader(fs);
StringBuilder sb = new StringBuilder();
while (s.Peek() >=0)
{
sb.Append("'" + s.ReadLine() + "',");
}
s.Close();
this.Cursor = Cursors.WaitCursor;
lblShowDetails.Text = "Retrieving data from the store...";
this.Refresh();
string accounts = sb.ToString().TrimEnd(",".ToCharArray());
string date1a = sb.ToString().TrimEnd(",".ToCharArray());
string date2a = sb.ToString().TrimEnd(",".ToCharArray());
try
{
ds.Tables.Clear();
if (sCustomer == "Customer1")
{
SqlDataAdapter da = new SqlDataAdapter("storedprocName", con);
da.SelectCommand.CommandTimeout = 0;
da.SelectCommand.CommandType = CommandType.StoredProcedure;
da.SelectCommand.Parameters.Add("@accounts", SqlDbType.VarChar);
da.SelectCommand.Parameters.Add("@date1", SqlDbType.DateTime);
da.SelectCommand.Parameters.Add("@date1", SqlDbType.DateTime);
da.Fill(ds, "xxx");
grdShowStats.DataSource = ds;
grdShowStats.DataMember = "xxx";
lblShowDetails.Text = "Done with Stats Enquiry...Waiting for next command";

I can't follow the logic of what you have there... so there must be very little.
Read the file one line at a time, use .Split to separate the values, set those values into the parameters, and then execute. Repeat as required.

hi,
I'm stuck at a multi-thred issue.
there is a class HibernateDAO<t> with utility methods. this class is never instanciated, since its methods are static.
HibernateDAO<t> has a reference to ISessionFactory, which should be singleton. but this ISessionFactory will be instanciated for each thread seperately (logging will produce the output multiple times).
can someone give me a hint why this behaviour occurs even after wrapping the access with _synclock variable?
public class HibernateDAO<T>
{
static ILog log = LogManager.GetLogger(typeof(HibernateDAO<T>));
static object _synclock = new object();
static ISessionFactory sessionFactory;
public static ISessionFactory SessionFactory
{
get {
lock (_synclock)
{
if (sessionFactory == null)
{
NHibernate.Cfg.Configuration cfg = new NHibernate.Cfg.Configuration().Configure();
cfg.AddAssembly(typeof(T).Assembly);
string conStr = (string)cfg.Properties["hibernate.connection.connection_string"];
log.Info("Trying to establish connection. Connectionstring: " + conStr);
sessionFactory = cfg.BuildSessionFactory();
}
}
return sessionFactory;
}
}
thanks in advance.

My guess would be it's because you're using generics (not a threading issue at all). Try running this:
static void Main(string[] args)
{
object o = HibernateDAO<object>.SessionFactory;
object s = HibernateDAO<string>.SessionFactory;
object q = HibernateDAO<object>.SessionFactory;
Console.WriteLine(object.ReferenceEquals(o, s) ? "o==s" : "o!=s");
Console.WriteLine(object.ReferenceEquals(o, q) ? "q==s" : "q!=s");
Console.ReadKey();
}
This wil get you:
o!=s<br />
q==s<br />
o and s are not the same because you've actually referenced two different classes entirely: One initialized with an object and one initialized with a string. o and q are in fact the same class of type HibernateDAO<object>, which is not the same as type HibernateDAO<string>.
Standards are great! Everybody should have one!

Your code here does not show HibernateDAO as static. Also it cannot be static as written due to the generics.
You have to make the class a strong type and define it explicitely as static in order to get a static class.
All you've done is define a static method inside an instance class.
You need something like this:
public static class Hibernate
{
...
}

Hi,
I have the following problem. On a page I have a multiple selection listbox.
It contains a lot of items. When items near the bottom are selected, and I
do a button click, the control jumps to the top. If there are a lot of items,
this can get very annoying, always having to scroll down to the selected
items (if I want to change them, or something).
Is there any solution so that after button click also the mouse position
remain unchanged.
Thanks & Regards

You can create a CultureInfo class and assign to the current thread... is that what you are looking for?

Thanks for your reply, using cultureinfo we can change the userinterface and IME for the particular form. but i want to change the whole operating system input locale. how could i do that one.
thanks in advance.

If the FormBorderStyle of the main form is set to None, the context menu on the taskbar is no longer accessible, which normally has menus Restore, Minimize, Move and Close when you right-click it.. is there a way at C# to still be able to display the context menu when the FormBorderStyle is set to None?

I have .NET 3.5 WinForms application. This contains form with
horizontal SplitContainer.
I set SplitterDistance to 30 in OnLoad()
However its value is 41 on OnFormClosing().
I want to obtain original value (30) for restore.
Any idea why value is changing automatically and how to get real value ?
It is interesting that SplitterDistance increases not by certain number of
pixels but by some factor.
First increase is from 30 to 41, i.e 11 pixels.
Seceon increase is frm 41 to a larger number of pixels.
This increasing seems to stop when SplitterDistance reaches to the value
which is set in Form Designer.
protected override void OnLoad(System.EventArgs e) {<br />
base.OnLoad(e);<br />
splitContainer1.SplitterDistance = 30;<br />
}<br />
<br />
protected override void OnFormClosing(FormClosingEventArgs e) {<br />
Settings.SplitterDistance = splitContainer1.SplitterDistance;<br />
base.OnFormClosing(e);<br />
}

When using a split window, the splitter will begin with the distance you provide it.
However it reacts based on changes to the forms in each panel. Adding a larger control to the top panel can push down the splitter as well as resizing the window. (Resize will cause it to try and maintain some type of relational sizing to the original size you created at design time) I found this out when building an 'Outlook-like' application and the button panel kept changing sizes.
I fixed the problem by hooking into the Resize event. Every time the form containing the split windows did a resize, I reset the splitter distance to the preferred location.

Thank you.
I changed setting to hold persent and added following code to resize method. Every time I re-open the form, Splitter moves up by a number of pixels. So top area becomes smaller and smaller until reaches to minimum height.
How to fix this ?
I have simple form containing ToolStrip and single horizontal splitter with DockStyle set to Fill. Top spitter are contains DataGridView and nbottom area contains multiline TextBox both with DockStyle set to Fill.
protected override void OnResize(EventArgs e) {<br />
if (Settings != null && Settings.SplitterDistance > 0m &&<br />
Settings.SplitterDistance < 100m) splitContainer1.SplitterDistance = (int)(Settings.SplitterDistance * (decimal)splitContainer1.Height / 100m);<br />
<br />
base.OnResize(e);<br />
}

In this example, you are computing the distance instead of defining a specific distance. So what is happening with this:
protected override void OnResize(EventArgs 3)
{
if ( Settings != null && Settings.SplitterDistance >0m && settings.SplitterDistance < 100m)
splitContainer1.SplitterDistance = ....your math
base.OnResize(e);
}
First you say you are only going to calculate a splitter distance if the distance is less than 100m.
You then compute by multiplying the distance by the height/100m. Your height is just a teensy bit smaller than your splitter distance.
So your height/100m will be a decimal since the height of splitcontainer1.Height being less than 100 causes the splitter distance to be less than 100. Not only will it be a decimal but it will be a decimal less than 1.
So now when you compute the splitter distance you are shrinking the distance by whatever the decimal amount is. So if my height is 50 then you've just moved in the splitter distance by 50%. ( distance * 50/100 -OR - distance * .50 )
Now you do something causing another resize event. Assuming you did not move the splitter itself then you are guaranteed of the fact that you are less than 100m. So when you catch that event you will move it once again.....only a smaller percentage this time. But each time you move it you will make it smaller and smaller because you are mulitplying it by a number smaller than 1.
Either do one of two things: leave it be where it ends up -- or determine a good place to have it in a fixed location. So maybe having it 100 pixels out is good. Then set the splitter distance to 100 every time you get a resize (unless the entire window is less than that).

No. Settings.SplitterDistance holds now upper pane height persent in range 0 .. 100% . I changed its name to SplitterDistancePercent.
Now you do something causing another resize event.
I do'nt understand this. Why you think that changing Splitcontainer SplitterDistance causes form resize event ?
leave it be where it ends up
My issue is that it does not remain in same place but moves up by some pixels every time form is re-opened.
determine a good place to have it in a fixed location
I need to allow end user to determine the good place by moving splitter by mouse at runtime. I save form splitter distance percent in form close event:
protected override void OnFormClosing(FormClosingEventArgs e) {<br />
Settings.SplitterDistancePercent = splitContainer1.SplitterDistance * 100m / splitContainer1.Height;<br />
SaveSettings();<br />
base.OnFormClosing(e);<br />
}
I want that splitter remain in this place when form is opened again.
It is not possible to add fixed place constant to code.

i m using the numeric validation for mobile...
if (txt_mob.Text != "")
{
Regex n = new Regex(@"(?<name>[0-9]|- |\+){10,20}");
Match v = n.Match(txt_mob.Text);
if (!v.Success || txt_mob.Text.Length > 20 || txt_mob.Text.Length < 10)
{
MessageBox.Show("Only digits '+' & '-' are allowed in Mobile and its size should be between 10 and 20 characters");
txt_mob.Focus();
}
}
its working ..but it takes 10 characters numeric and after that it is also accepting non-numeric characters please help
